STANFORD, Calif. -- Stanford has hired Delaware's Bernard Muir as its new athletic director.

Stanford provost John Etchemendy announced Muir's hiring Friday. He replaces Bob Bowlsby, who left last month after six years to become the new Big 12 commissioner.

Muir has almost 25 years of athletic administrative experience at Delaware, Georgetown, Notre Dame, Butler, Auburn and the NCAA. He has directed Delaware's athletic program since 2009, and was the athletic director at Georgetown from 2005-09.

Muir will take over a Stanford program that has won the Directors' Cup 18 straight years and is enjoying a football renaissance. The award is given annually by the National Association of Collegiate Directors of Athletics to the program with the most success in all sports.
